Specification of Letters Patent. Applipatioii filed September 10.1907. Serial No. 392.089.

Patented Dec. 24, 1907.

Be it known that I, ELISE .GoLTs'rEiN, subject of theEmperor of Germany, residing l at Cologne, Rhine Province, Emplre of Germany, have invented certain new and useful 5 Improvements in Bottle Caps or Closures for l Bottles, Jars, or other Receptacles, of which i the following isa specification.

' My invention relates to improvements in bottle caps or closures for bottles, jars, or other receptacles, and more particularly to capsule of sheet metal which can easily be torn and adapted to be rigidly connected to i.

an outer or inner shoulder provided on the capsule is formed, at its flat ortion, with a tongue-like thumb-piece whic can be easily and grasped by thefin ers of an 0 erator, in order to tear the capsu e and thereby to open the bottle or jar.

The object of the improvements is to provide a closure of this class, in which the strength of the capsule is increased by providing a comparatlvely small thumb-piece in said capsule, and which capsule can, notwithstanding, easily be torn by providing additional slits or weakened portions therein, which additional slits are so located as to be i met by the rents produced by pulling the thumbpiece and to again direct said rents away from eachother and near the circum- In the example illustratedin the drawing,

downwardly extending flange adapted to be bent or crimped into a groove formed on the upppr part of a bottle or jar. But I wish it to e understood, that my invention is not limited to the particular form of the capsule, or to the use of said capsule in combination with the bottle illustrated.

In the drawing, Figure ],,is a cross-section of a capsule showing the same in the tongue however being shown in a slightly ra sed position. Fig. 2, is a top view of Fi 1 illustrating the tongue portion and the a ditional slits or weakened parts, whereby'the i rent is directed back to the outer parts of the i capsule, and Fig. 3, is a cross-section of a bottle-provided with the improved closure.

Like letters of reference are used to indicate corresponding parts in all the views.

In the example illustrated, a bottle is formed near its mouth with a cap holder groove 1). A capsule c is provided with a depending flan e d adapted to be smoothly bent or criinped into or under the ca holder groove 1). Within said capsule, an on the top of the neck' of the bottle, a cork or sealing disk 2 and a sheet metal cork holder cliski, are located, which, by the pressure exerted by the capsule are, held in sealing contact with the face of the bottle.

Referring now particularly to Fig. 2, it

1 will be seen that the capsule c is provided, at

its flat portion, with a slit f. whereby a thumb-piece g is formed which can easily be bent upwards by the fingernail, as shown in dotted lines in Fig. 3, and/thereupon grasped by the fingers of the operator to tear the capsule. When thus pulling the tongue g, the

cap would tear substantially after the dotted lines shown in Fig. 2, so' that the rents would meet at a point away from the circumfer once. It would therefore be impossible to remove the cap. To avoid this, I provide further slits or scored portions h extending from a part of the line of the rent towards the rim of the capsule and diverging from the direction of the ull exerted on the tongue g. The rent wi I therefore follow the line of the slits or scored ortions h to the outer ends thereof, where om a new rent will be formedin an unweakened part of the capsule, which rent will strike a second set of slits or scored lines h, and soon, until the laslt rents meet the outer margin of the capsu e.

It will readily be understood, that the strength and holding power of my im roved closure is not materially impaired y the slits, because bridging portions of unweakened metal extend from one side of the circumference to the other, whereby a very safe and secure closure is produced, which is capable of withstanding the highest internal pressure ordinarily employed in bottled goods. And yet the closure can easily be removed, the rents being always directed outwards by the slits h.

I claim:

ceptacles, comprising a capsule made of a metal which can easily be torn and adapted to be secured to the mouth of said receptacle 1. A closure for bottles, jars, or other reand fOI'IIIBd With a slit providing a thumbpiece, and with weakened portions located at a distance from the ends of said slit and extending from thelines of rent produced when pulling said thumb-piece and diverging therefrom towards the rim of the capsule.

2. A closure for bottles, jars, or other receptacles, comprising a capsule made of a metal which can easily be torn and adapted to be secured to the mouth of said receptacle and formed with a slit providing a thumbpiece, and with a plurality of successively arranged weakened portions located at a distance from the ends of said slit and at a distance from one another and extending from the lines of rent roduced when pulling said thumbiece and diverging therefrom towards t e rim of the capsule.

3. A closure for bottles, jars, or other receptacles, comprising a capsule made'of a metal which can easily be torn and. adapted to be secured to the mouth of said receptacle and formed with a slit providing a thumbpiece, and with further slits located at a distance from the ends of said first named slit and extending from the lines of rent produced when pulling said thumb-piece and diverging therefrom towards the rim of the capsule.
